RCS3216F472CS Equivalent & Substitute Parts Reference
Part Overview
The RCS3216F472CS is a 4.7 kOhms ±1% 0.25W (1/4W) thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component features anti-sulfur and moisture-resistant construction, operating across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).
Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size and form factor), and environmental performance characteristics. Alternative sources provide equivalent functionality for applications requiring component availability, supply chain flexibility, or specific certifications such as automotive AEC-Q200 qualification.

Substitute Part Grouping Explanation
Substitution eligibility is determined by strict equivalence across the following critical parameters:
Electrical Equivalence:
- Resistance value: 4.7 kOhms
- Tolerance: ±1%
- Power rating: 0.25W (1/4W) or higher
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C to 155°C minimum
Mechanical Equivalence:
- Package type: 1206 (3216 Metric)
- Form factor: Surface mount chip resistor
- Number of terminations: 2
- Physical dimensions compatible with 1206 footprint
Environmental & Compliance Equivalence:
- RoHS3 compliance
- Moisture Sensitivity Level: 1 (Unlimited)
- Thick film composition
Parts meeting all three equivalence categories are classified as direct substitutes. Parts with higher power ratings (0.75W) are listed separately due to different thermal characteristics, though they remain mechanically and electrically compatible for most applications. Parts with "Not For New Designs" status are identified for reference in legacy system support only.

Engineering Selection Recommendations
Primary Substitutes (Active Status, 0.25W Rating):
AC1206FR-074K7L (YAGEO), CR1206-FX-4701ELF (Bourns Inc.), CRCW12064K70FKEA (Vishay Dale), KTR18EZPF4701 (Rohm Semiconductor), RC1206FR-074K7L (YAGEO), and RMCF1206FT4K70 (Stackpole Electronics Inc.) are direct functional equivalents to RCS3216F472CS. All maintain Active product status, identical electrical specifications, and ROHS3 compliance. These parts are suitable for new designs and ongoing production.
Automotive-Qualified Alternatives:
AC1206FR-074K7L, CRCW12064K70FKEA, KTR18EZPF4701, and RMCF1206FT4K70 carry AEC-Q200 automotive qualification. Selection of these parts is appropriate for applications requiring automotive-grade reliability and traceability.
Higher Power Rating Option:
CRCW12064K70FKEAHP (Vishay Dale) provides 0.75W power rating in the same 1206 package with AEC-Q200 qualification and pulse withstanding capability. This part is mechanically and electrically compatible but exhibits different thermal performance characteristics. Use only when higher power dissipation capacity is required.
Legacy System Support:
ERJ-8ENF4701V (Panasonic Electronic Components) carries "Not For New Designs" status. This part remains available for maintenance and repair of existing systems but should not be selected for new product development.
Frequently Asked Questions (FAQ)
Q: Can I substitute RCS3216F472CS with any of the listed alternatives without circuit modification?
A: Yes, all parts listed with 0.25W power rating and Active status are direct substitutes. They share identical electrical specifications (4.7 kOhms ±1%, ±100ppm/°C, -55°C to 155°C), package form factor (1206), and environmental compliance (ROHS3, MSL 1). No circuit redesign is required.
Q: What is the difference between the 0.25W and 0.75W versions?
A: CRCW12064K70FKEAHP provides 0.75W power rating compared to the standard 0.25W. Both occupy the same 1206 package footprint. The higher power rating allows greater current handling and heat dissipation. Use the 0.75W version only if your application requires increased power capacity; standard 0.25W parts are sufficient for most circuits.
Q: Are automotive-qualified parts (AEC-Q200) required for my application?
A: AEC-Q200 qualification is mandatory for automotive and safety-critical applications. For general industrial or consumer electronics, standard ROHS3-compliant parts without AEC-Q200 certification are acceptable. Verify your application requirements before selecting a qualified alternative.
Q: Why is ERJ-8ENF4701V marked "Not For New Designs"?
A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. The part remains available for legacy system support and repair. For new designs, select from Active status alternatives.
Q: Do all substitutes have the same physical dimensions?
A: All parts use the 1206 (3216 Metric) package with compatible footprints. Minor variations in seated height (0.024" to 0.030") do not affect PCB assembly or circuit function. Verify your PCB design accommodates the maximum height specification if clearance is constrained.
Q: What is Moisture Sensitivity Level (MSL) 1, and why does it matter?
A: MSL 1 indicates unlimited shelf life without moisture-related degradation. All listed parts carry MSL 1 rating, eliminating moisture sensitivity concerns during storage and handling. Standard storage conditions apply without special desiccant requirements.
Q: Can I use these substitutes in high-temperature applications?
A: All listed parts operate across -55°C to 155°C. This range covers most industrial and automotive applications. Verify your specific operating temperature requirements fall within this range before selection.
